Blind embroiderer Ah Ruan was involved in the "Embroidered Soul Case" because of her "heart-locking embroidery" - a "white silk neck" appeared on the embroidery screen of the deceased wife of a wealthy businessman, and she was falsely accused of being the murderer and imprisoned. The imperial guard Gu Yan was ordered to investigate the case and found half a piece of "Jingyang" jade hidden in her embroidered bandage, which together with the jade pendant she carried could be the symbol of "Jingyang Palace". The two went from confrontation to cooperation.
Ah Ruan relied on the residual energy of the "soul-inducing silk" to "touch and read memories". When repairing the embroidery, a scene of Gu's mother's death appeared: she gave the swaddling clothes to the old eunuch and told "it's time for the plum blossoms in Jingyang Palace to bloom." Gu Yan also discovers the old grudge between her mother and the main culprit of the "Embroidered Disaster Case", and the two people's backgrounds gradually emerge - A Ruan is the orphan of the prince, and Gu Yan is the "stand-in" raised by Gu's mother to protect her.
In order to seize the legitimate heir, the queen used the "soul-inducing silk" to control her memory and frame Gu's mother and Ah Ruan's parents. Ah Ruan and Gu Yan visited the palace at night and recovered the truth about the "Embroidery Disaster Case": Gu's mother was protecting the prince's orphan (A Ruan) and was framed by the queen for "controlling the prince with a heart-locking embroidery".
In the Jinluan Palace, Ah Ruan used the embroidery as evidence and Gu Yan used the sword as an oath to expose the queen's conspiracy. After the truth came to light, Gu Yan gave up his identity as a prince, reopened the "Xiu Yi Pavilion" with Ah Ruan, and used lock heart embroidery to protect the memories of ordinary people. When the plum blossoms bloomed, he held her hand and said, "I used to protect the imperial power, but now I only protect what you want to protect."
